7 Upgrades for the Traxxas Slash 4×4:

You have total control over your Traxxas Slash 4×4’s various features. Let’s take a look at the seven most important upgrades for the Traxxas Slash 4×4 and how much they’ll set you back.

1. Body Panel Kits

The Traxxas Slash 4×4 Kit is a mobile superstructure. For ultimate DIY adaptability, add your choice motor, digital speed control, servo, and radio system to the chassis.

The scale body of the Slash 4×4 is protected from the elements by an Exoskeleton cage that maintains scale accuracy. Install a roll cage if you want to push the chassis to the next level since it will offer it an advantage on difficult terrain.

It will cost roughly $45 if you simply get the top light set. The rear top and side roll sets, on the other hand, would set you back at around $90.

2. Skins & Wraps

If you’re concerned about the appearance of your Slash 4×4, you can choose from a variety of skins and coverings to make it look like a genuine predator of the night.

The skins are of exceptional quality, with a smooth, scratch-resistant surface. There’s also a choice between a comfortable matte finish and a more opulent glossy finish.

Depending on the variety and extent of your personalization, these skins, decals, and covers may cost anywhere from $10 to $65.

3. Motor & ESC

You’ll need a Traxxas Velineon brushless power system combination, which includes a brushless Velineon motor, to replace the motor and ESC.

For further dependability, you may use a 13-tooth pinion and the Slash VXL’s extruded aluminum driveshaft. By installing a splined drive hub on the front gearbox, you can guarantee that the draft shaft is in good working order.

If required, the user can replace the Traxxas motor with a genuine Traxxas motor from the manufacturer.

If the player wants to increase the Slash 4×4’s ESC, he can do so with third-party settings.

The cost of these ESC improvements will range from $70 to $200.

4. Wheels

The factory tires give excellent grip and add to the authenticity of the Slash 4×4 experience. Traxxas’ blue foam compound is used in the Slash tires, which gives the grip and traction needed to tackle even the most difficult terrain.

Wheel improvements might cost anything from $20 to $40. Wheels with a lower weight are usually less expensive, whereas tires with a higher weight are usually more expensive.

Weighted wheels for greater grip or lightweight tires for increased agility and speed are available if the user desires.

Aluminum improvements to your Traxxas Slash’s present suspension components are one of the most effective modifications.

Shocks, Shock Caps, Caster Blocks, and Turnbuckles are the primary upgrading elements among the suspension system’s parts and components.

Shock kits from Traxxas range in price from $14 to $69, while Shock Caps are priced from $14 to $25. Complete sets, on the other hand, cost $54 to $59.

Single Turnbuckler upgrading kits cost $6, while pairs cost $12 to $35. Aluminum caster blocks cost $19 to $49, and single Turnbuckler upgrading kits cost $6.
